1997 Universal Automatic #5.5 Dual Head CNC DrillModel 5.5 | S/N 3140 | CNC Series 2 Control | Dual Opposed HeadsOverviewThe Universal Automatic #5.5 is a high-speed, dual-end secondary operation machine designed to eliminate bottlenecks in high-volume production. This 1997 unit is the "Goldilocks" vintage—modern enough to feature the Series 2 CNC Control, yet built with the heavy cast-iron rigidity that made U.A.M. the industry standard for secondary ops.By utilizing Dual Opposed Heads, this machine performs simultaneous drilling, tapping, or milling on both ends of a part, effectively doubling the output of a standard single-head machine.Factory Specifications & Technical DataYear of Manufacture: 1997Head Configuration: Dual Opposed (Double-End Horizontal)Max Drilling Capacity: 1.25" (Mild Steel)Max Tapping Capacity: 1.00" (Mild Steel)Stroke per Head: 8.0" Maximum (Fully Programmable via CNC)Spindle Speeds: 475 to 3,100 RPM (Infinitely Variable)Spindle Motors: Dual 2.0 HP High-Torque (90V DC Drives)Spindle Nose: Industry Standard [Insert: e.g., #2 Morse or ER-32]Controller: Universal Automatic "Series 2" 2-Axis CNCInput Power: 208-230/460V, 3-Phase, 60HzMachine Weight: Approx. 3,500 lbs (Heavy Cast-Iron Base)Key Features & Dealer BenefitsSimultaneous Multi-End Machining: Factory-set logic allows heads to fire simultaneously, sequentially, or in a "peck" cycle, reducing production time by 50% compared to single-head setups.CNC Series 2 Precision: Unlike older pneumatic models, the electronic feed control ensures a constant chip load, providing superior depth control and significantly extending tool life.Rapid Approach & Retract: Programmed "Rapid" moves to the part face followed by precision "Feed" rates optimize cycle times for high-volume runs.Automated Fixturing Interface: The electrical cabinet is pre-wired for seamless integration with pneumatic collet fixtures, rotary dial tables, or bowl feeders.Production-Ready Base: Features a massive built-in coolant reservoir and full-length chip tray designed for continuous flood-coolant operations.
